MEAT CHOPPER.

Application filed October 17, 1924. Serial N0. 744,129.

To all whom it may concern:

Be it known thatI, lVILLrAM J. ANDER- soN, a subject of the King of Sweden, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Meat Choppers, of which the following is a speciiication, reference being had therein to the accompanying drawlng.

This invention relates to meat grinding machines and has special reference to an improved form of cutter head.

The principal object is to provide a materially improved formof cutter and other minor objects will become apparent in the further description of the invention.

In the accompanying drawings:

7 Figure 1 is a vertical central section through the discharge end of the casing or barrel of the cutter head:

Figure 2 is a rear elevation of the cutter head; and

Figure 3 is a front elevation of same.

1 represents the casing or barrel of a common meat cutter having an annular recess 2 in the extreme outer end thereof, the same being surounded with an externally screw threaded enlargement of the casing, as indicated at S, and about which the annular internally screw threaded head 4 is mounted to hold the perforated plate or grid 5 in position, all of which is common to meat grinders.

6 represents the shaft upon which the feeding screw 7 is mounted, they rotating together as is common. Upon the squared portion of the shaft 6, extending beyond the screw, is removably mounted my improve-d cutter head 8, it being circular in form and snugly fitting within the annular recess 2 in the casing. This head is cut-out or hollow in the back thereof preferably in four segmental portions indicated at 9. in the centor of each of which is a circular through hole 10. About each of these holes or openings 10 and on the face of the cutter head is mounted an annularly shaped: blade 11, the same being somewhat frusto-conical in shape, and having an annular flange 12 about the base thereof which fits snugly against the front face of the cutter head, while the opposite terminus of the frustoconical portion fits tightly against the inner face of the grid and is provided with but a narrow marginal face.

Each of these cutting blades are held in position upon the cutter head preferably by being somewhat recessed therein, and the flange 12 being provided with four countersunk notches 13 for registration with the heads of the screws 14, there being two of the latter for each knife, while there are four notches 13 upon each knife, thus permitting of the same being from time to time turned a quarter or more turns in their seat,

after slacking of the holding screws 14:,

when the latter may be again tightened retaining each knife in its subsequently adjusted position, in this manner preventing abnormal wear of any of the knives or the grid.

From the foregoing description of the cutter head it is apparent that four radially disposed webs 15 are formed thereupon,

which not only act as a reinforcing element for the head but have atendency to carry the meat or other substance being cut in individually divided portions, so that as little power as possible is wasted in the commingling, whereas in the ordinary cutter that portion directly adjacent the grid is substantially stationary.

It is apparent from the foregoingthat I have devised a novel form of cutter for meat grinders, exceptionally simple and of durable construction, and one that forms a novel form of cutting edge in that each knife is a complete circle and the cutter head is so arranged as to carry a volume of columns of the substance being cut directly adjacent each cutting knife, and, while various modifications may be resorted to without departing from the spirit of the invention, what I 1. A cutter head for meat grinders of the class described'comprising a circular body portion having a plurality of radially disposed recesses in the rearmost face thereof,

a circular opening through the center of each recessed portion, and an adjustable an-' claim and desire to secure by Letters Patent,

of a cutter head intermediate of the ried by the face of the head adjacent the grid and the screw rotatable with the latter grid, said knives frictionally engaging the and carrying a plurality of radially disgrid for the purpose described. 10 posed recesses upon the screw face thereof, In testimony whereof I hereunto aflix my said recesses terminating in circular opensignature.

ings away from the screw, and frusto-conically shaped adjustable cutting knives car- WILLIAM J. ANDERSON.
